Background: carotid/vascular MRI Figure 1. 3T magnetic resonance imaging (MRI) of atherosclerotic plaque in a right common carotid artery. The vessel wall is lined with complicated, lipid-rich plaque, which has a necrotic core (solid arrow). A thin fibrous cap can be seen in the bottom-left of the image (dashed arrow) Magnetic resonance arteriography (MRA) has for many years been used as a non-invasive means of producing an arterial lumenogram, an image of flow down the arterial lumen, from which the presence of significant stenosis could often be detected, if needed, by comparison to the comparatively normal flow in the contralateral vessel.
